Air-to-Water Heat Pump
• European/International Technical Standard setting the limits for voltage changes, voltage
fluctuations and flicker in public low-voltage supply systems for equipment with rated current ≤ 75
A.
• European/International Technical Standard setting the limits for harmonic currents produced by
equipment connected to public low-voltage systems with input current ≤16 A of
≻
75 A per phase.
Circuit Breaker Specification
Perform the electrical wiring work according to
the electrical wiring specifications:
• All wiring must comply with the local
requirements.
• Select a power source that is capable of
supplying the current required by the air
conditioner.
• Use a recognized ELCB(Electric Leakage
Circuit Breaker) between the power source and
the unit. A device to properly disconnect all the
supply lines must be fitted.
• Model of circuit breaker should be
recommended by authorized personnel only.

Point for attention regarding quality of the public electric power supply
This equipment complies with respectively:
- EN/IEC 61000-3-12 (1) provided that the short-circuit power Ssc is greater than or equal to the
minimum Ssc value at the interface point between the user's supply and the public system. It is the
responsibility of the installer or user of the equipment to consult the network operator if necessary, that
the equipment is connected only to a supply with Ssc value greater than or equal to the minimum Ssc
value.
